This application is a National Stage application of International Application No. PCT/EP2007/054717 filed May 15, 2007, which claims the benefit of U.S. Provisional Application No. 60/802,354, filed May 22, 2006, the entire contents of which is hereby incorporated herein by reference.

The present invention relates to new insecticidal methods of using 4-Amino-5-chloro-thieno[2,3-d]-pyrimidine compounds and salts thereof.

Animal pests destroy growing and harvested crops and attack wooden dwelling and commercial structures, causing large economic loss to the food supply and to property.

While a large number of pesticidal agents are known, due to the ability of target pests to develop resistance to said agents, there is an ongoing need for new agents for combating animal pests. In particular, animal pests such as insects and acaridae are difficult to be effectively controlled.

It is therefore an object of the present invention to provide methods and compounds having a good pesticidal activity, especially against difficult to control insects and acaridae.

It has been found that these objects are solved by 4-Amino-5-chloro-thieno[2,3-d]-pyrimidine derivatives of the general formula I:

Preparation Methods

4-Amino-5-chloro-thieno[2,3-d]pyrimidine compounds of formula I according to the present invention can be prepared starting from thiophen compounds (II) as described in EP 0447 891 B.

A thiophen derivative of formula (II)

wherein R¹ is defined as above, is reacted with a dialkyl amide (III)

wherein T¹ and T² are independently from one another C₁-C₄-alkyl or form together with the nitrogen a 5 to 7-membered saturated heterocyclus and R² is defined as above, in presence of an excess of a phosphoryl halogenide as e.g. 2 to 20 mol of phosphoryl chloride or phosphoryl bromide compared to 1 mol of (II) in order to provide a thieno(2,3-d)-pyrimidine derivative of formula (Ia)

wherein R¹¹ is chloro or bromo.

Compounds of formula (Ia) obtained as described above can be converted by substitution of the halogen atom in position 4 by another nucleophilic rest according to known methods as described in ‘The Chemistry of Heterocyclic compounds’, “The pyrimidines”, ed. D. J. Brown, J. Wiley & Sony, New York, London, Vol. 16, (1962); Vol. 16, Suppl. 1, Vol. 16, Suppl. 2 (1985).)

They are converted to the corresponding compounds of formula I by the substitution of R¹¹ by NR³A as described in EP-A 447 891.

Examples of suitable dialkyl-amides (III) are N,N-dimetyhl-formamide, N,N-dimethylacetamide, N,N-diethyl-formamide, N,N-diethyl-acteamide, N,N-dimethyl-propionamide and N,N-dimethyl benzoic acid amide.

As mentioned above, the reaction has to be conducted in presence of an excess of phosphoryl chloride or phosphoryl bromide compared to the thiophen derivative (II). Advantageously the reaction may take place with the phosphoryl halogenide as a solvent. Preferably 2 to 6 mol of phosphoryl halogenide are used per mol of the thiophen derivative (II).

In general the molar ratio of the thiophen derivative (II) to the N,N-dialkyl amide (III) is from 1:1 to 1:5.

The reaction is usually conducted in an inert solvent as chlorobenzole, nitrobenzole, benzoic acid methyl ester, methylene chloride, dichlorobenzol, trichlorobenzole, benzoic acid ethyl ester, chloroform, tetrachlorocarbon, one of the N,N-dialkyl amides listed above, trichloroethane, hexamethylphosphoric triamide (HMPT) or tetrachloroethylene. Preferred solvent are phosphoryl chloride and phosphoryl bromide or one of the N,N-dialkyl amides listed above.

The reaction has a sufficient reaction speed above 20° C. At temperatures above 150° C. the reaction specificy drops. Preferably the reaction is conducted in a temperature range of 50 to 110° C.

By the use of catalytic amounts of a lewis acid as potassium chloride, sodium chloride, iron (III) chloride, aluminium chloride, zinc chloride, tin chloride, antimony pentafluoride, boron trifluoride or titanium tetrachloride or of a basic catalyst as N,N-dimethyl aniline or N,N-diethyl aniline an increase of yield and an enhancement of reaction speed can be achieved.

Another process of preparation of 4-amino-5-chloro-thieno[2,3-d]pyrimidine compounds of formula I is provided by reacting according to common practise compounds of formula (IV)

wherein R¹ is defined as above, with an acid anhydride, that contains at least a rest R²—CO—, or a carbonic acid R²—COOH, or an adduct of a carbonic acid and a lewis acid, wherein R² has the respective meaning as described above, to compounds of formula (Ib):

Compounds of formula (Ib) are converted with a phosphoryl halogenid to compounds of formula (Ia) as defined above. It is suitable in certain cases to conduct this conversion in two steps, thereby isolating the intermediate compounds of formula (VI):

In general the acid anhydride or the adduct is used in amounts from 100 to 500 mol-%, preferably from 100 to 300 mol-%, in regard of compounds (VI).

The carbonic acid anhydrides containing at least one rest R²—CO—, can be provided out of two carbonic acids R²—COOH, as pivalic acid, propionic acid or acetic acid; or out of one carbonic acid R²—COOH and one oxo acid, as phosphoric acid or sulfuric acid.

Preferred carbonic acids R²—COOH are those with 1 to 4 carbon atoms, especially formic acid and acetic acid.

Further, adducts of a carbonic acid R²—COOH and a lewis acid, as zinc chloride, boron trifluoride and titanium tetrachloride are also suitable.

The conversion from (IV) to (Ib) is advantageously conducted in an inert solvent, as N,N-dialkyl amides, preferably N,N-dimethyl formamide and N,N-dimethyl acteamide, N-methyl-pyrrolidone, N,N-dimethyl propylene urea or hexamethylphosphoric triamide at temperatures from (−10) to 150° C., preferably from 20 to 120° C., more preferably from 80 to 120° C.

In order to isolate intermediate compounds (VI), the reaction temperature should be chosen from (−10) to 80° C.

In general a base as triethylamine, N-methyl-pyrrolidone or N,N-dimetyhl aniline should be added in an excess of 1 to 10-times, preferably in an excess of 1 to 5-times, compared to the carbonic acid anhydride, the carbonic acid or the carbonic-acid-lewis-acid-adduct.

The addition of a water removing agent as dicyclohexyl carboimid or a vilsmeier reagent can speed up the reaction and increase the yield of compounds of formula (Ib).

The hydroxy group in position 4 of compound of formula (Ib) can be substituted by chloro or bromo according to common practise, e.g. with phosphoryl chloride or phosphoryl bromide.

Finally chloro and bromo in position 4 is substituted by NR³A as described e.g. in EP-A 447 891.

Furthermore, by conversion of thiophen compounds of formula (II) with orthoesters (V), wherein R¹² is a C₁-C₄-alkyl, to derivatives of formula (VI), and subsequent cyclysation in presence of an amine NR³A, thieno[2,3-d]pyrimidine compounds of formula (I) according to the present invention can be obtained.

The latest described reaction scheme is known from DE-A 26 54 090. The thiophene derivative (II) and (IV) can be obtained according to the instructions disclosed in EP-A1-0193 885.

In order to obtain salts, which are suitable for agricultural or veterinary use, the 4-amino-5-chloro-thieno[2,3-d]pyrimidine compounds of formula I can be reacted with conventional salt builders as hydrochloric acid, hydrobromic acid, hydroiodic acid, sulfuric acid, phosphoric acid, formic acid, acetic acid, oxalic acid, benzene sulfonic acid, p-toluol-sulfonic acid, dodecylbenzene sulfonic acid, methyl bromide, dimethyl sulfate or diethyl sulfate in temperature range of 0 to 150° C., preferably 20 to 120° C.

The formation of the salt is usually conducted in a dissolving or diluting agent. Suitable are e.g. aliphatic hydrocarbons as n-pentane, n-hexane or petrol ether, aromatic hydrocarbons, as benzole, toluole or xylole, benzine or ethers as diethyl ether, methyltert.-butyl ether, tetrahydrofurane or dioxane, further ketones, as acetone, methyl-ethylketone or methyl-isopropyl-ketone, as well as halogenated hydrocarbons as chlorobenzole, methylene chloride, ethylenen chloride, chloroform or tetrachlor ethylene. Also mixtures of those solvents can be used.

For the preparation of salts of compounds of formula I the educts are employed usually in a stoichiometric ratio. The excess of one or the other component can be useful.

In the preparation methods described, the variables R¹, R², and R³ have the meanings as defined above, in particular the meanings mentioned as being preferred.

If individual compounds cannot be prepared via the above-described routes, they can be prepared by derivatization of other compounds I or by customary modifications of the synthesis routes described.

The reaction mixtures are worked up in the customary manner, for example by mixing with water, separating the phases, and, if appropriate, purifying the crude products by chromatography, for example on alumina or silica gel. Some of the intermediates and end products may be obtained in the form of colorless or pale brown viscous oils, which are freed or purified from volatile components under reduced pressure and at moderately elevated temperature. If the intermediates and end products are obtained as solids, they may be purified by recrystallization or digestion.

In the methods according to the invention the pests are controlled by contacting the target parasite/pest, its food supply, habitat, breeding ground or its locus with a pesticidally effective amount of compounds of formula I or with a salt thereof or with a composition, containing a pesticidally effective amount of a compound of formula I or a salt thereof.

“Locus” means a habitat, breeding ground, plant, seed, soil, area, material or environment in which a pest or parasite is growing or may grow.

In general, “pesticidally effective amount” means the amount of active ingredient needed to achieve an observable effect on growth, including the effects of necrosis, death, retardation, prevention, and removal, destruction, or otherwise diminishing the occurrence and activity of the target organism. The pesticidally effective amount can vary for the various compounds/compositions used in the invention. A pesticidally effective amount of the compositions will also vary according to the prevailing conditions such as desired pesticidal effect and duration, weather, target species, locus, mode of application, and the like.

The compounds of the invention can also be applied preventively to places at which occurrence of the pests is expected.

The compounds of formula I may be also used to protect growing plants from attack or infestation by pests by contacting the plant with a pesticidally effective amount of compounds of formula I. As such, “contacting” includes both direct contact (applying the compounds/compositions directly on the pest and/or plant—typically to the foliage, stem or roots of the plant) and indirect contact (applying the compounds/compositions to the locus of the pest and/or plant).

The aforementioned compositions are particularly useful for protecting crop plants against infestation of said pests or for combating these pests in infested plants.

For use in treating crop plants, the rate of application of the active ingredients of this invention may be in the range of 0.1 g to 4000 g per hectare, desirably from 25 g to 600 g per hectare, more desirably from 50 g to 500 g per hectare.

In accordance with one variant of the present invention, a further subject of the invention is a method of treating soil by the application, in particular into the seed drill, e.g. in form of a granular formulation containing compounds of formula I alone or in mixture with other active ingredients. This method is advantageously employed in seedbeds of cereal, maize, cotton and sunflower. For cereals and maize, the rates of application may depend from the active ingredients used, and may range between 50 and 500 per hectare for one active ingredient and between 50 and 200 g per hectare for the other active ingredient.

In the case of soil treatment or of application to the pests dwelling place or nest, the quantity of active ingredient ranges from 0.0001 to 500 g per 100 m², preferably from 0.001 to 20 g per 100 m².

The compounds of the invention may also be applied against non-crop insect pests, such as ants, termites, wasps, flies, mosquitos, crickets, or cockroaches. For use against said non-crop pests, compounds of formula I are preferably used in a bait composition.

The bait can be a liquid, a solid or a semisolid preparation (e.g. a gel). Solid baits can be formed into various shapes and forms suitable to the respective application e.g. granules, blocks, sticks, disks. Liquid baits can be filled into various devices to ensure proper application, e.g. open containers, spray devices, droplet sources, or evaporation sources. Gels can be based on aqueous or oily matrices and can be formulated to particular necessities in terms of stickyness, moisture retention or aging characteristics.

The bait employed in the composition is a product, which is sufficiently attractive to incite insects such as ants, termites, wasps, flies, mosquitos, crickets etc. or cockroaches to eat it. The attractiveness can be manipulated by using feeding stimulants or sex pheromones. Food stimulants are chosen, for example, but not exclusively, from animal and/or plant proteins (meat-, fish- or blood meal, insect parts, egg yolk), from fats and oils of animal and/or plant origin, or mono-, oligo- or polyorganosaccharides, especially from sucrose, lactose, fructose, dextrose, glucose, starch, pectin or even molasses or honey. Fresh or decaying parts of fruits, crops, plants, animals, insects or specific parts thereof can also serve as a feeding stimulant. Sex pheromones are known to be more insect specific. Specific pheromones are described in the literature and are known to those skilled in the art.

For use in bait compositions, the typical content of active ingredient is from 0.001 weight % to 15 weight %, desirably from 0.001 weight % to 5% weight % of active compound.

In the method of this invention compounds I may be applied with other active ingredients, for example with other pesticides, insecticides, herbicides, fertilizers such as ammonium nitrate, urea, potash, and superphosphate, phytotoxicants and plant growth regulators, safeners and nematicides. These additional ingredients may be used sequentially or in combination with the above-described compositions, if appropriate also added only immediately prior to use (tank mix). For example, the plant(s) may be sprayed with a composition of this invention either before or after being treated with other active ingredients.

In general, “parasiticidally effective amount” means the amount of active ingredient needed to achieve an observable effect on growth, including the effects of necrosis, death, retardation, prevention, and removal, destruction, or otherwise diminishing the occurrence and activity of the target organism. The parasiticidally effective amount can vary for the various compounds/compositions used in the invention. A parasiticidally effective amount of the compositions will also vary according to the prevailing conditions such as desired parasiticidal effect and duration, target species, mode of application, and the like.

The compositions, which can be used in the invention can comprise generally from about 0.001 to 95% of the compound of formula I.

Generally it is favorable to apply the compounds of formula I in total amounts of 0.5 mg/kg to 100 mg/kg per day, preferably 1 mg/kg to 50 mg/kg per day.

Ready-to-use preparations contain the compounds acting against parasites, preferably ectoparasites, in concentrations of 10 ppm to 80 percent by weight, preferably from 0.1 to 65 percent by weight, more preferably from 1 to 50 percent by weight, most preferably from 5 to 40 percent by weight.

A detailed list of plastics and elastomers as well as preparation procedures for the shaped articles is given e.g. in WO 03/086075.

Seed Treatment

The compounds of formula I are also suitable for the treatment of seeds in order to protect the seed from insect pest, in particular from soil-living insect pests and the resulting plant's roots and shoots against soil pests and foliar insects.

The compounds of formula I are particularly useful for the protection of the seed from soil pests and the resulting plant's roots and shoots against soil pests and foliar insects. The protection of the resulting plant's roots and shoots is preferred. More preferred is the protection of resulting plant's shoots from piercing and sucking insects, wherein the protection from aphids is most preferred.

The present invention therefore comprises a method for the protection of seeds from insects, in particular from soil insects and of the seedlings' roots and shoots from insects, in particular from soil and foliar insects, said method comprising contacting the seeds before sowing and/or after pregermination with a compound of the general formula I or a salt thereof. Particularly preferred is a method, wherein the plant's roots and shoots are protected, more preferably a method, wherein the plants shoots are protected form piercing and sucking insects, most preferably a method, wherein the plants shoots are protected from aphids.

The term seed embraces seeds and plant propagules of all kinds including but not limited to true seeds, seed pieces, suckers, corms, bulbs, fruit, tubers, grains, cuttings, cut shoots and the like and means in a preferred embodiment true seeds.

The term seed treatment comprises all suitable seed treatment techniques known in the art, such as seed dressing, seed coating, seed dusting, seed soaking and seed pelleting.

The present invention also comprises seeds coated with or containing the active compound.

The term “coated with and/or containing” generally signifies that the active ingredient is for the most part on the surface of the propagation product at the time of application, although a greater or lesser part of the ingredient may penetrate into the propagation product, depending on the method of application. When the said propagation product is (re)planted, it may absorb the active ingredient.

Suitable seed is seed of cereals, root crops, oil crops, vegetables, spices, ornamentals, for example seed of durum and other wheat, barley, oats, rye, maize (fodder maize and sugar maize/sweet and field corn), soybeans, oil crops, crucifers, cotton, sunflowers, bananas, rice, oilseed rape, turnip rape, sugarbeet, fodder beet, eggplants, potatoes, grass, lawn, turf, fodder grass, tomatoes, leeks, pumpkin/squash, cabbage, iceberg lettuce, pepper, cucumbers, melons, Brassica species, melons, beans, peas, garlic, onions, carrots, tuberous plants such as potatoes, sugar cane, tobacco, grapes, petunias, geranium/pelargoniums, pansies and impatiens.

In addition, the active compound may also be used for the treatment seeds from plants, which tolerate the action of herbicides or fungicides or insecticides owing to breeding, including genetic engineering methods.

For example, the active compound can be employed in treatment of seeds from plants, which are resistant to herbicides from the group consisting of the sulfonylureas, imidazolinones, glufosinate-ammonium or glyphosate-isopropylammonium and analogous active substances (see for example, EP-A-0242236, EP-A-242246) (WO 92/00377) (EP-A-0257993, U.S. Pat. No. 5,013,659) or in transgenic crop plants, for example cotton, with the capability of producing Bacillus thuringiensis toxins (Bt toxins) which make the plants resistant to certain pests (EP-A-0142924, EP-A-0193259),

Furthermore, the active compound can be used also for the treatment of seeds from plants, which have modified characteristics in comparison with existing plants consist, which can be generated for example by traditional breeding methods and/or the generation of mutants, or by recombinant procedures). For example, a number of cases have been described of recombinant modifications of crop plants for the purpose of modifying the starch synthesized in the plants (e.g. WO 92/11376, WO 92/14827, WO 91/19806) or of transgenic crop plants having a modified fatty acid composition (WO 91/13972).

The seed treatment application of the active compound is carried out by spraying or by dusting the seeds before sowing of the plants and before emergence of the plants.

In the treatment of seeds the corresponding formulations are applied by treating the seeds with an effective amount of the active compound. Herein, the application rates of the active compound are generally from 0.1 g to 10 kg per 100 kg of seed, preferably from 1 g to 5 kg per 100 kg of seed, in particular from 1 g to 2.5 kg per 100 kg of seed. For specific crops such as lettuce the rate can be higher.
